TYPOGRAPHICAL CASTING-MUERTE.

Specification of Letters Patent.

Application led July 28, 1916. Serial No. 111,765.

To all whom 'it may concern:

Be it known that I, GEORGE P. KINGSBURY, a citizen of .the UnitedStates, residin -at Brooklyn, in the county of Kings and tate of NewYork, have invented certain new and useful Improvements in TypographicalCasting-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotypemachines of the general organization represented in U. S. Letters Patentto O. Mergenthaler, No. 436532, wherein a type bar or slug is cast in aslotted mold against an assembled line of matrices presented momentarilythereto and confined between a pair of clamping jaws, and wherein theslug after casting is removed from the mold by an ejector which advancesfrom the rear' and pushes it forwardly between a pair of trimming knivesinto a receiving galley at the front of the machine.

In practice, it is frequently necessary to produce the type bars orslugs of different lengths to accord with the width or measure of thebody or columnv to be printed, and this practice necessarily involvesthe use of molds of appropriate length. It is also essential in mostinstances that both the ejector and the line clamping jaws be adjustedto correspond to the length of the mold in use or the slug to be casttherefrom. It sometimes happens, however, through carelessness orinexperience, that the operator failsr to make these adjustments, whichfailure often leads to disastrous results. For instance, if the ejectorblade is too lwide to enter the mold, serious damage is bound to occur,and the same is true if the distance between the clamping jaws is lessthan the length of thecomposed line; or if the distance between the jawsis greater than the length of the line, a bad squirt is apt to result. ll

is the object of my invention to obviate the' foregoing objections, andto that end,

I have provided mechanism which insures the'corresponding adjustments ofthe line clamping 4and slug ejecting devices. More specifically, I haveconnected both of these mechanisms to a common adjusting means, so thatthe adjustment of one effects the corresponding adjustment 0f the other..In

be made therein which will still be comprised within its spirit. Itherefore desire it to be understood that I do not limit myself to anyspecific form or embodiment, except in so far as such limitations arespecied in the claims.

Referring to the drawings:

Fig. 4 is a section on the line 4 4 of Fig. 3;

Fig. 5 is a similar view showing the parts in different relativepositions, and

Fig. 6 is a section on the line 6 6 of Fig. 5.

There are two general methods followed for casting type bars or slugs ofdifferent lengths, one involving the employment of a so-calledadjustable mold, i. e., one whose mold slot may be shortened orlengthened to the required extent, and the other involving the 'use of aplurality' of interchangeable molds having casting slots of the dierentlengths desired. In the present instance,

this latter method has been adopted for purposes of illustration. Theseveral molds, only one of which is shown, marked B, are carried by thedisk'B-1 (see Fig. 3) which is rotatably mounted upon the mold slide B2so as to present the selected mold first in a horizontal positionto-coperate with an assembled line of matrices, and thereafter to carrythe mold around to a vertical posiltion, as indicated, to .locate itinfront of the ejector mechanism which expels the slug therefrom. Y

During the casting operation, the composed line of matrices is supportedbefore the mold between the clamping jaws C and D suitably sustained inthe vise frame A. The left hand jaw D is mounted as usual to slidehorizontally in a guideway in the vise frame so that the distancebetween it and the opposing jaw C may be varied according to the lengthof line employed. The position of the jaw D is determined by theadjustable straight-toothed rod E slidably supported in the vise frameand passing through a nut or block (shown by dotted lines in Fig. 1)which is adapted to be shifted laterally to a slight extent under theinfluence of the justifying devices in the ordinary way. The rod E isconnected to the nut by the locking bolt or latch G mounted thereon andformed with teeth to engage those of the rod. In effecting theadjustment of the jaw D, the locking bolt G is first raised to disengageit from the rod E, and the latter is then moved endwise in one directionor the other as required. For this purpose, the rod is provided at itsouter end with the arm E2 to which is connected the bar or member E3extending toward the right across the top of the vise frame A andconnected to the operating devices later to be described. Before andafter the rod is thus moved, the locking bolt G is moved to its inactiveand active positions, respectively, these operations being carried outby means of the pivoted springactuated lever H and the underlyin bar I.The bar I is seated upon and carrie by the bar E3, the latter beinprovided with a series of buttons or protu erances (not shown) whichnormally engage in recesses or depressions formed in the under face ofthe bar I, so that when the bar I is moved longitudinally with respectto the bar E3, it will also be shifted or .cammed laterally to rock thelever H upwardly and disengage the connected bolt G from the rod E. Thespring I8 connected at one end to the bar E3 and at its opposite end tothe bar I serves to restore the latter to its original position on theformer and thus to allow the bolt G to be rengaged with the rod E. Theforegoing parts and their mode of operation are fully set forth in theKennedy U. S. Letters Patent No. 1,139,980, dated May 18, 1915, to whichreference may be had for further particulars, if desired.

The slug ejecting mechanism herein illustrated is of the kindrepresented in the U. S. Letters Patent to John R. Rogers, No. 967,796,dated August 23, 1910, comprising the series of parallel Ablades orsections F1 arranged one above another and guided between the verticalface of the mold slide B2 on one side and the fixedvertical plate F3 onthe opposite side. The several sections are free to move forward andbackward i11d9' pendently, and also so that any desired number may bebrought into action conjointly to form an ejector of a widthcorresponding to the length of the slug to be cast, while the othersections remain inactive in their backward position. These ejectorsections are actuated by the corresponding members F2, mounted ingrooves of the mold slide B2 and adapted to be coupled to the mainactuating slide F through the medium of the vertically adjustable barF4, which has its lower end arranged to travel forward and backward onthe rod F5 attached to the vertical slide F6. The slide F6 is adapted tobe raised and lowered to select vany desired number of the ejectorblades for use, or to eHect their operative connection with the mainactuating slide F. v

The foregoing parts taken from the two patents mentioned have beenselected merely vby way of example and to illustrate a preferredembodiment of my invention, such parts being in practical and commercialuse today. It should be understood` however, that my invention may beadapted to other constructions which'might require a totally differentform of mechanism from that herein illustrated. My invention is directedbroadly to any suitable means which will insure the correspondingadjustments of the line clamping and slug ej ecting mechanisms. In thepresent instance, such means comprise a common adjusting deviceconnccted to both mechanisms, so that their adjustments may be carriedout simultaneouslyv and to corresponding extents.

In the particular embodiment illustrated, the common adjusting device isin the form of an operating hand-lever M2 pivotally mounted at its rearend upon a transverse stud M3 fixed 'in the framework. Also pivotallymounted upon the stud M3 is a further lever O connected at its rear endto the vertical slide F6 controlling the adjustment of the ejectormechanism. These two levers are normally connected together in advanceof their pivot by means of a locking pin P, which may however, beoperated to disconnect them when desired, as will later be described.The connections between the operating lever M2 and the jaw adjustingmeans comprise a pair of vertical rods or links L1 and M1, the latterbeing pivoted at its lower end directly ALo the operating lever, and theformer to a hand plate L2 also pivoted thereon, as at L3, and formedwith' 'and provided at its forward end with 'a similar bevel gear Jmeshing with rack teeth I2 formedon the bar I, which controls the jawlocking means.

In eiiecting the adjustments of the parts, the operator grasps the leverM2, pressing in the hand plate L2 to disengage its etooth t L4 from thesector L5. This relativemove-4 ment of the hand plate shifts theconnected l rack L upwardly, effecting the independent rotation of thesleeve J2, which consequently moves the bar I longitudinally to therightto disengage the locking bolt G from the j aw adjusting rod E. Theoperating lever M2 is then moved upwardly or downwardly as re` quired,carrying with it both of the racks L and M, and causing the rotation oftheir respective bevel gears J and K, which thus shift the rods I and E3conjointly to the left or right according to the direction of movementof the operating lever to set the jaw D in the desired position. Thismovement of the hand lever M2 is also communicated to the operatinglever O for the ejector adjusting lslide F3, which is accordingly movedupwardly or downwardly as the case may be to select the requisite numberof the individual ejector blades F1 or to control their connection withthe actuating slide F. After the parts have been adjusted in the abovemanner, the operator releases his hold upon the operating lever, and theconnected plane L2 isI then pushed away by its spring L3 to restore theengagement of its locking tooth L1 with the sector L5 and thus to holdthe parts in their operated position. The locking movement of the plateL2 also restores, through the connections described, the rengagement ofthe locking bolt G with the toothed rod E, which holds the jaw D in itsadjusted position. In short, when the distance between the clamping jawsC and D is varied, the width of the ejector blade is altered tocorrespond, these adjustments being effected simultaneously and by meansof a common operating device.

It is sometimes desirable to cast short` lines on long bodies, or thelike, in which event itis necessary to set the clamping jaws at adistance apart less than the length of the mold slot, and it may bedesired todo this without disturbing the width of the ejector blade. Forthis reason, I have provided means whereby the operating lever M2 may bedisconnected from the ejector adjusting slide F3 at will, so that thelever may be operated to effect the independent adjustment of thei lineclamping jaws. the present-instance, such means comprise 'the a. lockingpin `P before referred to, which passes transversely through holes orapertures in the levers M2 and O. The aperture in the lever M2 is openfrom below so as to permit it to straddle the locking pin or to bedisengaged therefrom, but near its inner face the lever is formed with aair of inwardly projecting lips M1 partly dlosin the aperture andadaptedto embrace a xed collar P1 on the locking pin. Normally,thefcollar1 P1 is held within the lipsM1 by a spring j P3, as in Fig. 4,but when the pin is drawn to the right a ainst the action of the spring,the collar is s ifted out of engagement with the lipsv andv passes intothe enlarged and unobstructed portion of the aperture, as in Fig. 5, inwhlch position of the `parts the lever may clear the pin and be free tobe moved upwardly independently of the lever O (see Fig. 6). The lockingpin is held iny the latter or inactive position by means of a cam shapedpiece P8 fixed thereon and arranged to coperate with a beveled sectorplate N fixed to the pivot stud M3, the sector plate being of sufficientcircumferential extent to allow the disconnection of the parts invarious adjusted positions. The engagement of the piece P3 with theplate N also serves to maintain the ejector adjusting slide F-3 in itsset position during the independent operation of the lever M2. Thelocking pin P is provided with a handle P2 to facilitate itsmanipulation.

As previously stated, I have shown my invention merely in preferredform'and by way of example and as applied to a specific style ofmechanism,. but obviously many modifications and alterations therein,and in its mode of adaptation, will suggestthemselves to those skilledin the art without departure from its scope.
